Model 719 Autosampler

VARIABLE VOLUME AUTOSAMPLER


The Model 719AL autosampler is a syringe style, partial or full-loop injection autosampler that accepts 8mm, 12mm or 15mm vials or microplates. Three injection volume ranges are available by choosing a 50µL, 250µL or 2mL syringe. Designed for HPLC and LC/MS applications, the 719AL provides superior precision, accuracy, flexibility and reliability to your system.

BENEFITS

The Model 719AL autosampler is a syringe style, partial or full-loop injection autosampler that accepts 8mm, 12mm or 15mm vials or microplates. Three injection volume ranges are available by choosing a 50µL, 250µL or 2mL syringe. Designed for HPLC and LC/MS applications, the 719AL provides superior precision, accuracy, flexibility and reliability to your system. Emulating a manual HPLC injection process, the 719AL has zero sample loss and can reproducibly make 1µL injections from micro inserts containing as little as 3µL of total sample.


BENEFITS

> Accurate injection volumes from 0.06µL to 2mL using partial or full loop

> Internal and external needle rinse to eliminate carryover

> Optional vial trays available in three vial sizes plus microplates

> Automated dilutions, mixing, derivatizations and sample preparations

> Selectable needle depth

> Simple to use and maintain

> System interface through RS-232, IEEE, Contact Closures and I2C

> Customized software feature available
